Menu Structure
Table 9 illustrates the complete hierarchy of menus and parame-
ters for the EconoMi$er X system.
The Menus in display order are:
•STATUS
• SETPOINTS
• SYSTEM SETUP
• ADVANCED SETUP
•CHECKOUT
•ALARMS
NOTES:
1. For 2 speed unit, under SYSTEM SETUP: EQUIPMENT= CONV,
AUX2 I = W, and FAN TYPE = 2 SPEED.
2. More sophisticated controller setups, including for DCV or power
exhaust, are available by referring to Table 11 options.
3. Fan speed options are:
1) 1 Speed
2) 2 Speed
3) 2 Speed: 1 Heat, 1 Cool.
4) 3 Speed: 1 Heat, 2 Cool.
4. Do not use 3 speed setting for LC units.
IMPORTANT: Table 9 illustrates the complete hierarchy. Menu
parameters may be different depending on configuration. For
example, none of the DCV parameters appear for a system that
does not have a DCV (CO
2
) sensor.
IMPORTANT: The default setting on the W7220 controller is
for a “Fan Type” with 2 speed, which is correct for 2 speed
units. For a 1 (single) speed unit, the setting under SYSTEM
SETUP > FAN TYPE must be changed to 1 speed.
